Hp color laserjet black print fades to the bottom of the page.

You didn't say that you swapped out the toner.
Let's come back to that point later.

Put paper in the manual feed tray.
Print something.
As soon as the paper feeds halfway into the printer, open the top cover.
Pull out the toner, look down at the paper. Is it mostly black?
If the answer is yes....replace the toner.
Vacuum out the inside of the printer and print again.
I think you have a bad toner cartridge

Hi,

Just remove all the removable parts from your printer including trays, toners, etc.

Shake your print toners so that the toner powder inside is mixed well equally throughout the drum inside.

Replace all the parts back and try printing and may be this should work fine for you.

Please provide back your ratings.
Thanks

Open top cover and remove toner, shake toner cartridge and try a test print. IF image good then problem is low toner level in cartridge.

you are running out of toner

my hp color laserjet 2600n black toner always show message flshing what is the problem ?

Hi,

If the toner cartridges are "refills" that might explain some of your print quality issues. Unfortunately, HP only has 2 replacement parts for that model, the fuser and the ETB (Transfer belt) both would require a technician to replace. Check the transfer belt of any tears or punctures. Careful not to touch it, oils from your skin can cause quality issues as well. If at all possible replace all the toners with ones that were working fine.

Is the toner orginal?
Try printing a test page and see how that comes out?
Try shaking the toner it might be stuck on one side.

Thanks

Press Green Tick, Right, -> System Setup -> Right, Right, -> Print Quality, Right -> Replace Supplies. Change from stop at out, to override at out. It'll let you print, and you'll get loads more out of your toner before the pages start to fade.

This is caused by toner contamination in the laser scanner unit, it is quite a complex job removing and cleaning the laser scanner. I would suggest you contact HP regarding the repair.
